September 2025 was the 3rd warmest September on record for our planet, following 2023 (1st place) and 2024 (2nd place). The last 12-months have been about 1.51°C above the 1850-1900 pre-industrial average.

Are these the world's oldest rocks? Yes, probably, maybe, likely. Words by me

1.5 C is nowhere near as ‚safe‘ as we once thought.

Warming of +1.5 °C above pre-industrial levels is too high for the Greenland and Antarctic ice sheets, and even the current climate forcing of +1.2 °C is likely to lead to several meters of sea-level rise, according to a study in Communications Earth & Environment. 🧪
Warming of +1.5 °C is too high for polar ice sheets - Communications Earth & Environment
Warming of +1.5 °C above pre-industrial levels is too high for the Greenland and Antarctic ice sheets, and even the current climate forcing of +1.2 °C is likely to lead to several meters of sea-level rise, meaning that only a return to +1 °C or lower will avoid extensive loss and damage to coastal populations, according to a synthesis of recent evidence.

The measles outbreak in Texas is reminding me of the public letter Roald Dahl wrote about losing his daughter to measles in 1962, just before the vaccine was publicly available.
Excerpt from a public letter Roald Dahl wrote encouraging people to vaccinate their children. Olivia, my eldest daughter, caught measles when she was seven years old. As the illness took its usual course I can remember reading to her often in bed and not feeling particularly alarmed about it. Then one morning, when she was well on the road to recovery, I was sitting on her bed showing her how to fashion little animals out of coloured pipe-cleaners, and when it came to her turn to make one herself, I noticed that her fingers and her mind were not working together and she couldn’t do anything. “Are you feeling all right?” I asked her. “I feel all sleepy,” she said. In an hour, she was unconscious. In twelve hours she was dead. The measles had turned into a terrible thing called measles encephalitis and there was nothing the doctors could do to save her. That was twenty-four years ago in 1962, but even now, if a child with measles happens to develop the same deadly reaction from measles as Olivia did, there would still be nothing the doctors could do to help her. On the other hand, there is today something that parents can do to make sure that this sort of tragedy does not happen to a child of theirs. They can insist that their child is immunized against measles. I was unable to do that for Olivia in 1962 because in those days a reliable measles vaccine had not been discovered. Today a good and safe vaccine is available to every family and all you have to do is to ask your doctor to administer it.
